摘　　要：应对近地小行星撞击风险,开展小行星防御问题研究是未来国际天文界、航天界等多个领域所面临的重大科学和技术挑战。本文以面向近地小行星防御问题为背景,系统介绍了几何力学与控制研究及其在该领域的应用现状和前景,并根据小行星防御的实际问题,提出了“一来,二去,三绕,四控”的近地小行星防御策略和相关的亟待解决的科学问题,阐明了几何力学与控制在该防御策略下的重要作用,为近地小行星的防御理论提供了一种新的理论基础,为我国建设近地小行星防御系统提供理论参考。Dealing with the risk of near-Earth asteroid(NEA)impact and conducting research on asteroid defense is a major scientific and technological challenge for the international astronomy,aerospace and other fields in the future.This paper systematically introduces the research on geometric dynamics and control and its application status and prospects in the field against the background of NEA defense.Based on the actual problems of asteroid defense,this paper proposes a NEA defense strategy of“Coming first,Going second,Circling third,Control fourth”and related scientific problems that need to be solved urgently,and clarifies the important role of geometric mechanics and control in this defense strategy,It provides a new theoretical basis for the near Earth asteroids defense,and a theoretical reference for the construction of defense system of NEA in China.
